When putting its own mark on classic casualwear, <b><a href=" http://www.selfridges.com/cat/boss-green/" style="text-decoration: none"><font color="black">Boss Green</font></a></b> makes sure to home in on the minutiae. Ticking off the textbook details like a sportswear checklist, this polo shirt by the German diffusion line features a soft collar rendered in fine stripes, ribbed trims at the short sleeves with the same tonal pattern and, at the top button of the half-placket, a few contrasting stitches in the label’s eponymous shade.
